To all whom t may concern:

Be it known that we. EDWARD J. RICHARD- SON and .hues ROY RICHARDSON, citizens of the United States, residing at Chamberlain. in the county ot Brille and State of South Dakota, have invented new and useful Improvements in Self-Adjusting Driving-Belts, of which the following is a specification.

This invention deals with belts and has particular reference to power transmitting belts such as are used in connection with machinery.

The primary object of the invention resides in the. provision of an elastic belt. of the above mentioned character.I capable ot' adjusting itself to the pulleys` or surface over which it passes. with a view of preventing vibration of the ditlerent runs of the belt, and thereby eliminating noisey and all possibility of the belt jumping a' pulley.

Another importantobject of' the invention resides in the novel means of fastening the adjacent ends of the belt together.

The nature, and advantages of the invention Will be better understood 'from the tollowing description when taken in connection with 'the accompanying drawing. the invention residing in the construction. combination and arrangement of parts as claimed.

In the drawing forming part of this speciication like numerals of reference indicate similar parts in the several views and whereinzl Figure l is a perspective view of the belt when used.

Fig. 2 is a top plan view.

Fig, 3 is an enlarged vertical sectional View taken on line of Fig. 2.

Fig. 4 is an enlarged horizontal sectional view taken on line 4 4 of Fig. 2.

As shown in this'particular instance, the, device forming the subject matter of our invention comprises a plurality ot' spaced parallel coil springs 10 having their convolutions normally arranged in contacting engagement, while mounted upon the springs are a plurality of leather strips ll. These strips arearranged transversely of the springs l0 and are provided with openings 12 for the reception of the springs, the strips ll being closely associated, or in other Words arranged in face to face contact. lt

might here be stated that one or more springs 10 may be employed, the number of springs depending upon the desired width el the belt.

The ends of' the belt as a unit can be secured together in various ways, use being eratively associated 'for the reception ot aT Cotter pin l? which latter is adapted to also pass transversely through the. particular leather strip ll which receives the overlapped cxtensions l5. The pin li' of course holds the ends ot' the belt together. the con struction providing a flexible couplingy tor the latter. Maniliestly we have provided a belt ot' the class in question 4which b v reason ol its elasticity is capable ot adjusting itself to the pulleys A over which it is trained. the. belt possessing the proper tension to permit the belt to pass noiselessly over the pulleys without vibrating. thereby eliminating to a largel degree the possibility of the -belt leaving one or both of the pulleys.

lVhen the belt is used in connection with flanged pulleys the. belt can be stretched to permit the same to be trained over the same without uncoupling the adjacent ends of the belt.

lVhile it is believed that from the Yloregoing description the nature and advantages of the invention will be apparent, we desire. to have it understood that what is herein shown and described is merely illustrative of one einluuliment oi the invention to which we do not limit ourselves. and that such changes may be resorted to when desired as lall within the scope of what is claimed.

lVhat is claimed is:-

A belt oi' the character described comprision a plurality of springs, a plurality ol leather strips arranged in l'ace to lace contact` and having alined openings lo receive said springs, a pin threaded in eacll end of the springs and having a head formed with The extensions l5 (it course are proa reduced apertured extension, the exten- :v1-flexible couplingr is provided for the ad- 10 sions on the heads of the adjacent endsfof jacentends of the belt.
